Definitions

  • the invention relates to a device for filleting fish with a saddle for receiving the astride, gutted fish and with a rotating pair of circular knives, between whose knives the saddle for filleting the fish can be moved, the distance between the two circular knives corresponding to the thickness of the saddle is changeable.
  • a device of a similar design is described and shown in FR-A 1 094 257, an elastically mounted pair of circular knives lying below two contact surfaces which protrude obliquely downwards from the saddle.
  • An upper pair of circular knives is mounted so that the distance between the knives is constant.
  • the invention has for its object to provide a device of the type specified in such a way that the distance between the circular knives corresponds to the thickness of the fish that is placed on the saddle, which in turn should be adapted to the thickness of the fish.
  • pressure members for the fish are provided above the saddle and on its two sides, which can be designed as resiliently abutting rollers on the fish.
  • the saddle has suction elements for sucking the fish onto its side surfaces.
  • a knife is provided in the working direction in front of the circular knives and above the saddle in the longitudinal center plane thereof. This knife cuts the fish in the middle from the back down to the backbone. Two following deflectors then deflect the cut meat parts to the side before the two circular knives carry out the filleting. In this way, the meat content above the backbone, which is particularly large with a wide backbone, is not lost.
  • FIG. 1 schematically shows a base plate 10 with a longitudinal guide for a saddle 12 designed as a plate, which can be displaced in the longitudinal direction in the direction of the double arrow shown.
  • the drive for the displacement movement is not shown any further.
  • the thickness d of the saddle 12 can be adapted to the size of the fish 14 to be filleted by exchanging the saddle.
  • the gutted fish 14 is astride put on the saddle 12, the tail end 16 pointing forward in the direction of advance of the saddle 12.
  • the upper edge thereof has transverse incisions 18 and is provided with a step-shaped shoulder 20 in the region of the tail end 16.
  • Circular knives 22 arranged parallel to one another are provided, each of which is rotatably mounted on a pivot lever 24 about a horizontal axis.
  • the rotary drive for the circular knife 22 is also not shown.
  • the two pivot levers 24 are pivotally mounted on the base plate 10 about a vertical axis 26.
  • a feeler arm 28 is attached to each pivot lever 24, the free end of which extends up to the saddle 12 and carries a feeler roller 30 which bears against a side surface 32 of the saddle 12.
  • Pressure elements 34 are provided which are designed as compression springs and act on the feeler arm 28 in order to press the feeler roller 30 resiliently against the side surface 32 of the saddle 12.
  • the distance between the two circular knives 22 adjusts to the thickness d of the saddle 12 so that the said distance is only slightly greater than the thickness d, so that the meat portion cut out of the fish 14 during filleting and containing the bones is so thin as possible.
  • rollers 36 resiliently resting laterally on the fish 14 ensure that the fish 14 lies closely against the saddle 12.
  • the same purpose has a pressure roller 38 resiliently abutting against the fish 14 from above.
  • suction holes 40 may be provided in the region of the upper edge of the saddle, which are connected via a suction line 42 to a suction source, not shown.
  • the suction bores 40 also ensure that the fish 14 lies closely against the side surfaces 32 of the saddle 12.
  • the thickness d of the saddle 12 used is determined by the backbone width of the fish to be filleted. In the case of larger fish in particular, there is a large amount of meat above the backbone.
  • a knife 44 is provided in front of them and above the saddle 12 in the longitudinal center plane thereof, which knife 44 can be designed as a circular knife or as a fixed knife blade.
  • the knife 44 is preferably vertically adjustable, as indicated in FIG. 1 by an adjusting screw 46, so that the back of the fish is cut in the longitudinal direction up to the backbone.
  • two lateral, wedge-shaped deflection members 48 Upon further advancement through the saddle 12, two lateral, wedge-shaped deflection members 48 immediately grasp the incised meat portions and deflect them to the side before they can be grasped by the two circular knives 22. This measure further increases the filleting yield.
